Description
Technical Field
[0001] This utility model relates to the field of injection molding equipment technology, and in particular to an automated injection molding equipment. Background Technology
[0002] In current plastic product manufacturing, injection molding is a widely used process. Most mainstream injection molding machines adopt a semi-automatic processing method, which requires the operator to manually place the mold to be injected into the mold clamping mechanism of the injection molding machine. After the operator starts the injection molding machine to perform actions such as pressing the mold and injecting the plastic material into the mold cavity, the injection molding machine releases the mold, and the operator removes the entire mold containing the molded product from the injection molding machine. The operator then removes the solidified product from the mold and places the empty mold back into the injection molding machine to prepare for the next injection cycle.
[0003] However, this existing semi-automatic injection molding mode has a bottleneck in injection molding efficiency. It relies on manual operation. In the entire process, the two key steps of placing the mold and taking out the mold containing the finished product are entirely dependent on manual operation by workers. Furthermore, during the entire process of workers taking out the mold, demolding the product, and replacing the empty mold, the injection molding machine itself is in a paused or idle state, which restricts the overall production efficiency of the injection molding process.

[0016] After injection molding is completed, the turntable rotates again at a certain angle, causing another set of upper and lower molds to move to the bottom of the injection molding device for injection molding, while the set that has been injection molded moves to the top of the cooling seat.

[0027] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 , Figure 2 and Figure 5 .
[0028] The present invention discloses an automated injection molding equipment, including a worktable 1; Two spaced-apart first slots 11 are passed through the workbench 1; a sleeve 12 is passed through the workbench 1, the sleeve 12 is fixedly connected to the workbench 1 and is located at the center of the workbench 1, a bearing 122 is sleeved on the outside of the sleeve 12, the bearing 122 is close to the top of the sleeve 12, and a connecting ring 121 is sleeved on the outside of the bearing 122; a turntable 2 is rotatably connected to the workbench 1, and the connecting ring 121 is fixedly connected to the bottom of the turntable 2. In this embodiment, the turntable 2 is preferably a hollow structure, so that the sleeve 12 is located inside the hollow of the turntable 2; Furthermore, a first gear 22 is fixedly connected to the bottom of the turntable 2. In this embodiment, the first gear 22 is preferably a hollow ring structure. The turntable 2 and the first gear 22 are coaxial, and the first gear 22 is close to the edge of the turntable 2. Furthermore, the workbench 1 is provided with a drive mechanism 3, which is connected to the turntable 2. The drive mechanism 3 includes a drive motor 31. The drive motor 31 is fixedly connected to the bottom of the workbench 1. The output shaft of the drive motor 31 passes through the workbench 1. The output shaft of the drive motor 31 is fixedly connected to a second gear 311. The second gear 311 is located at the top of the workbench 1. The first gear 22 is meshed with the second gear 311. The output shaft of the drive motor 31 drives the turntable 2 to rotate via the second gear 311. In this embodiment, the drive motor 31 drives the turntable 2 to rotate 120° each time.
[0029] The turntable 2 has multiple second slots 23 arranged at intervals. In this embodiment, it is preferred that there are three second slots 23, which are arranged around the center of the turntable 2. In this embodiment, it is preferred that the three second slots 23 are spaced 120° apart.
[0030] Please refer to Figures 1-4 .
[0031] A lower mold 212 is fixedly connected to the second slot 23. The bottom of the lower mold 212 covers the second slot 23, and a molding cavity is opened on the top of the lower mold 212. An upper mold 211 is provided on the upper cover of the lower mold 212. A material channel runs through the upper mold 211 and is connected to the molding cavity. Furthermore, grooves are provided on both sides of the upper mold 211.
[0032] The top of the workbench 1 is provided with a pressing area, and two first slots 11 and the pressing area are arranged around the center of the turntable 2. In this embodiment, the two first slots 11 are preferably spaced 120° apart, and the pressing area is preferably spaced 120° apart from the first slots 11. Furthermore, three ball seats 13 are fixedly connected in the pressure area of the worktable 1. One ball seat 13 is close to the sleeve 12, and the other two ball seats 13 are close to the edge of the turntable 2 to prevent the rolling ball 131 from being located below the second slot 23. The ball seat 13 is equipped with a rolling ball 131, which touches the bottom of the turntable 2.
[0033] The workbench 1 is equipped with a lifting mechanism 4, on which a first lifting platform 41 is slidably connected. The lifting mechanism 4 includes a lifting cylinder 42 and a second lifting platform 43. The lifting cylinder 42 is fixedly connected to the bottom of the workbench 1, and the output shaft of the lifting cylinder 42 is fixedly connected to the top of the second lifting platform 43. Three guide rods 431 are fixedly connected to the top of the second lifting platform 43. The output shaft of the lifting cylinder 42 is parallel to the guide rods 431. One guide rod 431 passes through the sleeve 12 and is slidably connected to the sleeve 12. The other two guide rods 431 pass through the workbench 1 and are slidably connected to the workbench 1. The guide rods 431 are fixedly connected to the bottom of the second lifting platform 43, and the ball 131 is located below the second lifting platform 43. Furthermore, the top of the first lifting platform 41 is provided with an injection molding device 411, and the second lifting platform 43 has a through hole, with the injection port 412 of the injection molding device 411 located inside the through hole. Driven by the drive motor 31, the turntable 2 rotates, and one set of upper molds 211 and lower molds 212 moves to the bottom of the injection molding device 411. The output shaft of the lifting cylinder 42 pushes the first lifting platform 41 to descend. The first lifting platform 41 pulls the second lifting platform 43 to descend through the guide rod 431, so that the second lifting platform 43 and the turntable 2 clamp the set of upper molds 211 and lower molds 212, so that the injection port 412 of the injection molding device 411 is connected to the material channel, thereby injecting the molding material into the molding cavity. Since the downward pressure generated by the descent of the second lifting platform 43 is transmitted to the turntable 2 through the upper molds 211 and lower molds 212, the worktable 1 supports the turntable 2 through the rolling balls 131 in the pressure zone, thereby sharing the downward pressure on the turntable 2. After the injection is completed, the output shaft of the lifting cylinder 42 pulls the first lifting platform 41 to rise and reset.
[0034] Please refer to Figure 2 and Figures 5-8 .
[0035] The bottom of the workbench 1 is provided with a cooling mechanism 5 and a heating mechanism 6. A cooling seat 51 is slidably connected to the cooling mechanism 5, and a heating seat 61 is slidably connected to the heating mechanism 6. The cooling seat 51 and the heating seat 61 are respectively located below the two first slots 11. Furthermore, both the cooling mechanism 5 and the heating mechanism 6 include a mounting base 52 and a sliding plate 521; one end of the mounting base 52 is fixedly connected to the bottom of the workbench 1, and the other end of the mounting base 52 is fixedly connected to a drive cylinder 53; two parallel guide rails are fixedly connected to the mounting base 52, and four sliders are fixedly connected to the sliding plate 521, with the four sliders of the sliding plate 521 respectively slidably connected to the two guide rails of the mounting base 52; the output shaft of the drive cylinder 53 is fixedly connected to the sliding plate 521, and the output shaft of the drive cylinder 53 is parallel to the guide rails; the cooling base 51 is fixedly connected to the sliding plate 521 of the cooling mechanism 5, and the heating base 61 is fixedly connected to the sliding plate 521 of the heating mechanism 6; Furthermore, a flow channel is provided inside the cooling base 51, and both ends of the flow channel are connected to air inlets 511. The outlet and return ends of the external refrigeration mechanism are respectively connected to the two air inlets 511. Chilled water is injected into the flow channel through one of the air inlets 511 through the outlet end of the external refrigeration mechanism. The chilled water exchanges heat with the cooling base 51, reducing the temperature of the cooling base 51. After the heat exchange is completed, the chilled water enters the external refrigeration mechanism again through the other air inlet 511 from the return end of the external refrigeration mechanism for re-cooling. Furthermore, a heating wire 611 is embedded in the top of the heating base 61, and the heating wire 611 is electrically connected to an external power source; the external power source provides electrical energy to the heating wire 611, so that the heating wire 611 generates heat to heat up the heating base 61.
[0036] Driven by the turntable 2, the upper mold 211 and lower mold 212 that have completed injection molding move above the cooling seat 51. The cylinder of the cooling mechanism 5 pushes the slide plate 521 to slide and rise on the mounting seat 52, so that the cooling seat 51 passes through the first slot 11 and the second slot 23 in sequence and contacts the bottom of the lower mold 212, thereby cooling the lower mold 212 and causing the rubber material in the molding cavity to solidify and form. Driven by the turntable 2, the cooled upper mold 211 and lower mold 212 move above the heating seat 61. The cylinder of the heating mechanism 6 pushes the slide plate 521 to slide and rise on the mounting seat 52, so that the heating seat 61 passes through the first slot 11 and the second slot 23 in sequence and contacts the bottom of the lower mold 212, thereby heating the lower mold 212 and avoiding the problem that the temperature of the lower mold 212 and the upper mold 211 is too low, and the material solidifies too quickly in the material channel and molding cavity during injection molding, and the material cannot enter the molding cavity area.
[0037] The workbench 1 is equipped with a clamping mechanism 7, on which a gripper 71 is slidably connected. The clamping mechanism 7 includes a clamping cylinder 72 and a slide rod 73. The clamping cylinder 72 is fixedly connected to the top of the workbench 1, and the output shaft of the clamping cylinder 72 is fixedly connected to a slide block 721. The gripper 71 is fixedly connected to the slide block 721 and is located above the heating seat 61. The slide rod 73 is fixedly connected to the workbench 1, and the slide block 721 is slidably connected to the slide rod 73. The output shaft of the clamping cylinder 72 pulls the slide block 721 to slide down on the slide rod 73, so that the gripper 71 approaches the upper mold 211. The two gripping arms of the gripper 71 respectively clamp the grooves on both sides of the upper mold 211. The output shaft of the clamping cylinder 72 pushes the slide block 721 to slide up and reset on the slide rod 73, so that the gripper 71 clamps the upper mold 211 and the lower mold 212 to separate the molds. The output shaft of the clamping cylinder 72 pulls the slide block 721 to slide down on the slide rod 73, so that the upper mold 211 covers the top of the lower mold 212 to close the mold.
[0038] The workbench 1 is equipped with a feeding mechanism 8, which is close to the heating mechanism 6. The feeding mechanism 8 is equipped with a rocker arm 81 and includes a feeding cylinder 82, an insert, and a feeding conveyor belt 84. In this embodiment, the feeding cylinder 82 is preferably a dual-output shaft cylinder. The feeding cylinder 82 is fixedly connected to the bottom of the workbench 1. One end of the output shaft of the feeding cylinder 82 is fixedly connected to a feeding motor 83. The output shaft of the feeding motor 83 passes through the output shaft of the feeding cylinder 82, and the output shaft of the feeding motor 83 is located at the center of the output shaft of the feeding cylinder 82. Furthermore, a limiting groove is provided on the outer side of the feeding cylinder 82, and a limiting rod 821 extends from one end of the output shaft of the feeding cylinder 82. The limiting rod 821 is parallel to the output shaft of the feeding cylinder 82 and is slidably connected within the limiting groove. The limiting groove constrains the output shaft of the feeding cylinder 82 to slide axially only, thus preventing the output shaft of the feeding cylinder 82 from rotating. Furthermore, one end of the rocker arm 81 is rotatably connected to the other end of the output shaft of the feeding cylinder 82, and the insert passes through the rocker arm 81 and the output shaft of the feeding motor 83, so that the output shaft of the feeding motor 83 drives the rocker arm 81 to rotate synchronously; the other end of the rocker arm 81 is fixedly connected to a pneumatic suction cup 811, and the external compressor is connected to the pneumatic suction cup 811. Furthermore, the unloading conveyor belt 84 is fixedly connected to the outside of the worktable 1, and the rocker arm 81 drives the pneumatic suction cup 811 to move back and forth above the heating seat 61 and above the unloading conveyor belt 84. After the upper mold 211 and lower mold 212 separate, the output shaft of the unloading motor 83 drives the rocker arm 81 to rotate at a certain angle, causing the pneumatic suction cup 811 to move above the molding cavity. The output shaft of the unloading cylinder 82 pushes the unloading motor 83 to descend, causing the pneumatic suction cup 811 to contact and adsorb the product on the lower mold 212. The output shaft of the unloading cylinder 82 pulls the unloading motor 83 to rise and reset, and the pneumatic suction cup 811 removes the product from the molding cavity of the lower mold 212. The output shaft of the unloading motor 83 drives the rocker arm 81 to rotate at a certain angle and reset, causing the pneumatic suction cup 811 to move above the unloading conveyor belt 84. The output shaft of the unloading cylinder 82 pushes the unloading motor 83 to descend, causing the pneumatic suction cup 811 to place the product above the unloading conveyor belt 84 and release the product. The output shaft of the unloading cylinder 82 pulls the unloading motor 83 to rise and reset, and the pneumatic suction cup 811 moves away from the unloading conveyor belt 84, which then sends the product out.
[0039] Please refer to Figures 1-8 .
[0040] The upper mold 211 is placed on the lower mold 212, and the drive motor 31 drives the turntable 2 to rotate 120°, so that the three sets of upper molds 211 and lower molds 212 move above the pressing area, above the cooling seat 51 and above the heating seat 61 respectively; the first set of upper molds 211 and lower molds 212 move to the bottom of the injection molding device 411, and the lifting cylinder 42 pushes the first lifting platform 41 to slide down to clamp the upper mold 211 and lower mold 212. The injection port 412 of the injection molding device 411 then connects with the material channel to perform injection molding. After injection molding is completed, the lifting cylinder 42 pulls the first lifting platform 41 to slide upward and reset, thereby releasing the upper mold 211 and lower mold 212 that have completed injection molding; the drive motor 31 drives the turntable 2 to rotate 120° again, so that the second set of upper mold 211 and lower mold 212 moves to the bottom of the injection molding device 411 for injection molding, while the first mold that has completed injection molding moves to the top of the cooling seat 51; the drive cylinder 53 of the cooling mechanism 5 pushes the cooling seat 51 to pass through the first slot 11 and the second slot 23 in sequence to contact the lower mold 212, cooling the lower mold 212 and causing the rubber material in the lower mold 212 to solidify and form. After the second set of upper molds 211 and lower molds 212 complete injection molding and the first set of upper molds 211 and lower molds 212 complete cooling, the drive motor 31 drives the turntable 2 to rotate 120° again, so that the third set of upper molds 211 and lower molds 212 move to the injection molding device 411 for injection molding. The second set of upper molds 211 and lower molds 212, which have completed injection molding, move to the cooling seat 51, and the first set of upper molds 211 and lower molds 212, which have completed processing, move to the heating seat 61. The clamping cylinder 72 pulls the clamping jaw 71 down, so that the clamping jaw 71 approaches and clamps the upper mold 211. The clamping cylinder 72 pushes the clamping jaw 71 up to reset, completing the separation of the upper mold 211 and lower mold 212. At the same time, the drive cylinder 53 of the heating mechanism 6 pushes the heating seat 61 to pass through the first slot 11 and the second slot 23 in sequence to contact the lower mold 212, so as to heat up the lower mold 212. The unloading motor... The output shaft of cylinder 83 drives rocker arm 81 to rotate at a certain angle, causing pneumatic suction cup 811 to move above the molding cavity. The output shaft of unloading cylinder 82 pushes unloading motor 83 to descend, causing pneumatic suction cup 811 to contact and adsorb the product on lower mold 212. The output shaft of unloading cylinder 82 pulls unloading motor 83 to rise and reset, and pneumatic suction cup 811 removes the product from the molding cavity of lower mold 212. The output shaft of unloading motor 83 drives rocker arm 81 to rotate at a certain angle and reset, causing pneumatic suction cup 811 to move above unloading conveyor belt 84. The output shaft of unloading cylinder 82 pushes unloading motor 83 to descend, causing pneumatic suction cup 811 to place the product above unloading conveyor belt 84 and release the product. The output shaft of unloading cylinder 82 pulls unloading motor 83 to rise and reset, and pneumatic suction cup 811 moves away from unloading conveyor belt 84, and unloading conveyor belt 84 sends the product out. The clamping mechanism 7 drives the gripper 71 to descend, repositioning the upper mold 211 onto the lower mold 212, and the gripper 71 rises to reset; at the same time, the heating seat 61 slides to reset; the turntable 2 rotates again at a certain angle, allowing the mold assembly to enter the next injection molding operation.
[0041] This utility model provides an automated injection molding equipment. The upper mold is placed on the lower mold, and the turntable is rotated at a certain angle by the drive mechanism, so that a set of upper and lower molds are moved to the bottom of the injection molding device. The lifting mechanism drives the first lifting platform to slide down to clamp the upper and lower molds, and the injection molding device then performs injection molding.
[0042] After injection molding is completed, the turntable rotates again at a certain angle, causing another set of upper and lower molds to move to the bottom of the injection molding device for injection molding, while the set that has been injection molded moves to the top of the cooling seat. At this time, the cooling seat, driven by the cooling mechanism, slides and passes through the first and second slots in sequence to contact the lower mold, thereby cooling the lower mold and allowing the rubber material to solidify and form.
[0043] After cooling is complete, the cooling seat slides back to its original position; the turntable continues to rotate at a certain angle, moving the upper and lower molds, now in the injection molding process, between the grippers and the heating seat; the clamping mechanism drives the grippers to descend and clamp the upper mold, then the grippers rise to their original position, completing the separation of the upper and lower molds. Simultaneously, driven by the heating mechanism, the heating seat slides and sequentially passes through the first and second slots to contact the lower mold, heating it; the unloading mechanism drives the rocker arm to rotate at an angle, moving the pneumatic suction cup above the lower mold and adsorbing the solidified product; subsequently, the rocker arm rotates back to its original position, completing the product removal.
[0044] Next, the clamping mechanism drives the grippers to descend, repositioning the upper mold cover onto the lower mold, and the grippers rise to their reset positions. Simultaneously, the heating seat slides back to its original position. The turntable rotates again at a certain angle, allowing the upper and lower molds to enter the next injection molding cycle.
